Description
Technical field
The present invention relates to technical field of animal, more particularly, to a kind of low albumen Sheep Fattening mixed feed and its
Preparation method.
Background technique
Mutton is excellent tonic product, and it is the good merchantable brand of strengthening by means of tonics that nutritive value is abundant, the development and patient the old and the weak to baby
It is special that nourishing conditioning plays the role of.In northwest China area, Ningxia Tan Sheep first national Application of Animal Genetic money as China
Source gene pool list, mutton have the notable features such as fresh and tender mellowness, full of nutrition.In recent years, in view of priority protection ecology ring
Under the policy in border, the feeding and management method of Ningxia Tan Sheep is gradually from herding naturally to half drylot feeding or drylot feeding transformation.Since sheep known for its fine thick wool is raw
The change of production mode and feed type, especially fine fodder lead to sheep known for its fine thick wool body nutrition in the excessive use of scale livestock farming
It is unbalance, to produce certain negative effect to indexs such as nutritional ingredients in its meat, it is caused to lose original wind
Taste and mouthfeel, and then meat is caused to decline.
Simultaneously as the market factor changes, dregs of beans price fluctuation is obvious, and bring in traditional high protein ration cultivation
The greenhouse gas emission got worse such as increases at the environmental problems.Currently, reducing the low of protein additive amount by supplementary feeding amino acid
Protein daily food has become the hot spot of each feed manufacturing emterprise research.Therefore, it researchs and develops a kind of with protein utilization
High, nitrogen discharge less, can effectively improve the production performance of mutton sheep, improve quality of mutton, while the low albumen of high financial profit is continuous
Sheep fattening mixed feed, becomes very necessary and urgent.
In view of this, the present invention is specifically proposed.

Comparative example 1
This comparative example is not in addition to including rumen bypass lysine and rumen bypass methionine in the raw material of mixed feed, remaining is the same as real
Apply example 5.
Effect example 1
In order to filter out more particularly suitable feed mode, what the present invention was also specially prepared embodiment 5 and comparative example 1
Mixed feed has carried out the side that free choice feeding group, 0.8 times of free choice feeding feeding group, 0.6 times of free choice feeding feeding group are fed
Case.The Ningxia Tan Sheep 60 (wether 36, ewe 24) for selecting 7 monthly ages health, weight close, is randomly divided into 6 groups, every group of castrated ram
Sheep 6, ewe 4, by the mixed feed that embodiment 5 and comparative example 1 are prepared, 0.8 times of sheep known for its fine thick wool voluntary feed intake and
0.6 times is fed, specific to be grouped are as follows:
Test group A: mixed feed (free choice feeding) made from feeding comparative example 1,
Experiment group B: mixed feed (free choice feeding) made from feeding embodiment 5,
Test group C: mixed feed made from feeding comparative example 1 (by 0.8 times of feeding of voluntary feed intake),
Test group D: mixed feed made from feeding embodiment 5 (by 0.8 times of feeding of voluntary feed intake),
Test group E: mixed feed made from feeding comparative example 1 (by 0.6 times of feeding of voluntary feed intake),
Test group F: mixed feed made from feeding embodiment 5 (by 0.6 times of feeding of voluntary feed intake).
Test carries out 84 days, and butchers after the end of the test to sheep, weighs carcass weight, calculates dressing percentage；Measure it
The bicipital muscle of arm and longissimus dorsi muscle yellowish pink, pH, percentage of water loss, cooking loss, cooked meat percentage, drip loss, shearing force, result such as table 1
Shown in~4:
Table 1: the influence that different-energy is horizontal and supplementary feeding rumen bypass lysine and rumen bypass methionine are to Productivity of Tan Sheep
As seen from the above table, above-mentioned experiment group B was adopted compared with test group C, test group F compared with test group E days compared with test group A, test group D
Appetite is respectively increased 12.1%, 4.5% and 0.4%, and daily gain is respectively increased 28.2%, 20.5% and 4.0%；Test group simultaneously
B, test group D can reduce feedstuff-meat ratio compared with test group A, test group C respectively, reduce 11.3% and 13.1% respectively, into
And improve production performance.
Table 2: the influence that different-energy is horizontal and supplementary feeding rumen bypass lysine and rumen bypass methionine are to sheep known for its fine thick wool Slaughter
As seen from the above table, supplementary feeding rumen bypass lysine and rumen bypass methionine butcher Ningxia Tan Sheep under identical energy level
Performance has no significant effect.With the reduction of energy level, Slaughter weight, carcass weight and GR value (content of fat in body value) are in
It is remarkably decreased.
Table 3: different-energy level and supplementary feeding rumen bypass lysine and rumen bypass methionine are to sheep known for its fine thick wool longissimus dorsi muscle meat
Influence
As seen from the above table, supplementary feeding limiting amino acid can reduce cooking loss and improve cold cuts under identical energy level
Rate, addition amino acid cooking loss reduce by 12.0%, 13.3% and 8.3% respectively, and 6.5%, 6.5% and is respectively increased in cooked meat percentage
4.0%.
Table 4: different-energy level and supplementary feeding rumen bypass lysine and rumen bypass methionine are to sheep known for its fine thick wool bicipital muscle of arm quality
It influences
As seen from the above table, under identical energy is horizontal, supplementary feeding amino acid can reduce cooking loss and improve cooked meat percentage, addition
Cooking loss reduces by 17.1%, 5.2% and 8.8% respectively after amino acid, and 12.4%, 3.2% and is respectively increased in cooked meat percentage
4.8%.
Therefore, by above-mentioned table 1~4 it is found that under same feeding level (under free choice feeding；Under 0.8 times of free choice feeding group,
Under 0.6 times of free choice feeding group) addition amino acid group grows fastly than not adding amino acid group, and it is with good meat quality.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
Row equivalent replacement；And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme.
